Drawing on a video - how to change the animation speed?
on Jun 11, 2017 at 1:12:25 pm

Hi, i'm new to After Effects - i've just done a simple "drawing" on my video - like this one -






The problem is - the animation is too fast, so i would like to make it slower, or in other words, each frame should last for a couple of frames instead of just one.
How can i do that?

also, how can i copy a draw from one frame into another frame?

thank you!

this is very basic...but hit u twice and you should see something that lasts 1 frame..try to extend it with your mouse and if there are keyframes they will need to be spaced out to the ends of that layer.

Thank you, Richard. I'm sorry, i'm new to AE and i can't manage to do it.
I'm pressing U but i can't see a place where i can change the frames.
The drawings for all the frames were done, now i need to have each frame changed from 1 frame to 3, is there a way to change it for the entire composition?

Also, how can i copy-paste each frame with the drawing of it?

Thanks.

i dont see any length of time on your brush strokes...and it Should be all the way through the timeline...Although it does start from where you are in the timeline..make sure you are at the beginning and try again.

if you are painting on a video, then it has to be in sync with the video. simply adding more frames to each brush will make it slower, but it won't be in sync with the video anymore...

having said that, if you want to add more frames to a stroke, press PP to reveal your brush strokes and simply stretch and reorder them like ordinary layers.


if you need to make each frame last 3 frames you could also use the time stretch feature for the layer and set it to 300% if you want to triple the time it takes for each stroke:

if it's before you even start drawing, you could set your frames to last a custom number of frames and not just 1 if you set your duration to custom.



you might want to change a tool and use photoshop video timeline for your rotoscoping work. it has onion skin and more advanced features. Ae's paint tool is very limited. here's one artist who works this way: https://vimeo.com/ruffmercy

WOW, THANK YOU SO MUCH FOR YOUR HELP!
I've found a solution, to export my composition on a green screen and "strech" to fit my desired speed in Premiere.

My only last question is how can i copy a drwaing from one frame and paste it to the next frame?

i really appriciate your kind help,
thank you so much.
